REMOVABLE GALK FOR HO-RSESHOES Specification of Letters Patent.

Patented Feb. 3,1914.

Application filed February 7, 1913. Serial No. 746,770.

To all whom it may concern Be it known that I, THoMAs H. IVARNER, acitizen of the United States, residing in the city and county of Denverand State of Colorado, have invented certain new and useful Improvementsin Removable Calks for Horseshoes; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

My invention relates to improvements in removable calks for horse shoesand consists of a means for removably attaching calks to shoes and inmaking said means adjustable to fit shoes of difierent sizes.

One of the objects of the invention is to provide a device which shallhave a double clamping effect, making the liability of its becomingloose upon the shoe practically negligible.

Another object of the invention is to utilize the calk proper as one ofthe clamping elements.

A third object is to make the clamp adjustable for shoes of differentsizes.

Other objects will appear hereinafter as I proceed with the descriptionof that embodiment of the invention which, for the purposes of thepresent application, I have illustrated in the accompanying drawing, inwhich:

Figure 1 is an under face view of a horse shoe provided with my improvedremovable calks. Fig. 2 is a cross sectional view taken upon the line22, Fig. 1. Fig. 3 is a cross section upon the line 33, Fig. 1. Fig. 4is a detail perspective of the calk. Fig.

5 is a detail perspective of one of the clamp ing elements. Fig. 6 is adetail perspective of another of the clamping elements.

The same reference numerals refer to like parts in each of the views.

In the drawing, which forms a part of this specification, the numeral 5refers to a horse shoe of ordinary and well known form. IVhen the calkswhich are integral with the shoe become worn down and consequentlyuseless as a preventive against slipping, new sharp calks made inaccordance with my invention may be applied without removing the shoefrom the horses foot and without tools, other than a wrench.

My invention includes L-shaped members 6 and 7 both of which upon theinner side of the upright portions are serrated at 8, in order thatthe'serrations may bite into the metal of the horseshoe when the members6 and 7 are clamped together. Lips 9 extend inwardly from the upperextremities of the upright portions of each member, the lips 9 beingadapted to engage the upper surface of the shoe and thus assist inmaintaining the calk in place.

The horizontal portion of the member 6 has a threaded shank 10preferably integral therewith, and is also provided with a threadedperforation 12, the purpose of which will be described present-1y. Theupright portion of the member 7 below the serrations 8, is perforated at13, the wall of the perforation being smooth. The horizontal portion ofthe same member has a slot 14 therein, running longitudinally, said slotbeing slightly wider than the diameter of the threaded opening 12. Theperforation 13 is of sufficient size to receive the shank 1O loosely,when the members 6 and 7 are assembled, a nut 15 being then threadedupon the shank 10 and caused to clamp the parts together after which alocknut 16 is threaded upon the shank to bear against the nut 15. I

The calk 17 has the usual wedge shape with a flat surface 18 upon itsupper side. A. shank 19 preferably integral with the calk extendsupwardly from the surface 18, the shank 19 being of a size to slidefreely in the slot 14 but having threads adapted to fit those of theperforation 12. When the device is to be applied to a shoe, the calk 17is turned anti-clockwise until the horizontal portions of the members 6and 7 are free to slide readily upon each other when the device isplacec upon the shoe and the nuts 15 and 16 tightened. The calk 17 isthen grasped by its flat sides and screwed up until the horizontalportion of the member 7 is firmly clasped between the horizontal portionof the member 6 and the flat upper surface 18 of the calk 17. Of course,if preferred, the shank 19 of the calk 17 need not be inserted in theperforation 12 of the member 6 until the members 6 and 7 have beensecured by the nuts 15 and 16.

It will be apparent that when the calks 17 have been worn downconsiderably, new ones may be substituted even without the removal ofthe members 6 and 7 from the shoe, which is a very important feature ofmy invention.

It is obvious that minor chan es in the details of construction may bemade without departing from the spirit of my invention as set forth inthe appended claim.

I claim as my invention:

In combination, two L-shaped members, the horizontal portions of whichare arranged to extend toward each other, and the upright portions ofwhich are adapted to grasp a horseshoe, the horizontal portion of onemember lying upon the horizontal portion of the other member, the lowerhoriceive said shank, and means for drawing 25 toward each other theupright portions of said L-shaped members.

In testimony whereof I affix my signature in presence of two witnesses.
